Patient being burned by tea and not informing the family

My dad has been at Pholoso hospital for a few weeks now and the nurse did not bother to let us know when they were moving him from medical ward to ICU. After a week of him being in ICU I went to visit him only to find him with burns on his thighs when I die the sister who was in charge she told me the burn had been there when he was transferred . Went back to Medical ward and a nurse by the name of Joyce coil not tell me when the burn had happened and how come none of the family members was told about it when We asked her for the report or exact date she could not give us the report.She then called Surgical ward manager who was on duty on the day, he went through the patients file and there was no burn recorded, as s family we really concerned that if they can burn a patient with tea what else can they do and not tell the family. We were told that this will be investigate, we highly disappointed with the hospital and it’s nurses their level of professionalism is not acceptable
